I'm not agree with you. The game already looks good on 2 textures.
Moreover. New texture resolution will not change anything. A similar article about bad graphics will appear. Also do not forget - everyone has different computers. There are countries where people do not even upgrade the computer. In some countries, people think about what to pay for their studies, car repairs, and so on.
I understand that even so weak computers will disappear. But then the developers themselves will decide the solution.
At the moment, our respected IndieStone guys are spending a lot of time and effort on optimization. It is better to raise the topic not about improving graphics, but about a full transition from Java to Visual.
The problem of my computer is in a weak processor. For the good burned out.
2 core processor 1.9 <==The problem of my computer (was previously a 4-core 2.3 processor. Which for me and my games was more than enough.)
4 gb of RAM
1 gb video

I recommend you the Cartographer profession. he draws more detailed maps.
You will have to determine where you are. Also, do not forget to put labels on the map, this will help you quickly remember the location of important objects.
You decide what to do - choose a profession and draw all kinds of maps. Choose a line - and draw simple maps. Or find a journal in the game, and also draw only simple maps.

There is a profession - Cartographer.
There is a feature - Novice cartographer.
I personally found the magazine in 30 minutes of play. You needed Be patient.
Any Paper city map in the game is an image. With the depicted text on it (The text is drawn, which is inconvenient !!! YOU HEAR DEVELOPERS !!!))))). Therefore, you do not need to include English.
The text in Annotated Map, is the only text, that depends on the selected language in the game.
